摘要
目的采用64排螺旋CT重建正常成人的双侧上胫腓关节,测量活体上胫腓关节坡度,与裸骨测量结果比较,探讨该测量方法的准确性及其临床意义。方法选取正常成年男女志愿者各100名,年龄18～90岁,行双下肢64排螺旋CT扫描,重建胫腓骨全长。选用角尺测量上胫腓关节面与腓骨干纵轴的夹角(∠A)和上胫腓骨关节面与水平线的夹角(∠B)。运用统计学单因素方差分析原理验证测量方法准确性。结果∠A范围为56.16°～57.45°,x=56.80°±6.59°,M=56.70°,两侧比较无显著性差异(t=0.308,P=0.758)。∠B范围为32.17°～33.44°,x=32.80°±6.49°,M=32.90°。相关一回归研究结果示∠A和∠B比较,有显著性差异(t=51.87,P<0.01),两者呈负相关(r=-0.952,P=0.00)。结论利用64排螺旋CT重建上胫腓关节测量结果与裸骨关节面测量结果一致,证明该方法精确、方便、无创,便于临床应用,并建立大样本数据库。
Objective To establish the distributed database of the Chinese people＇s slope of proximal tibiofibular joint by reconstituting the adult normal knee joints with 64-row spiral CT, and to compare the result with bare joint data- base. Methods Totally 200 healthy adult volunteers, 100 females and 100 males, aged from 18 to 90 years old were en- rolled in this study. 64-row spiral CT was used to scan the both lower extremities. And the angle of slope of the longitudi- nal axis of the fibula and the articular surface （ angle A） , the angle of horizon of the proximal tibiofibular articular surface and the horizontal line （angle B）. Results Angle A was ranged from 56. 16° to 57.45°, x = 56. 80°±6. 59°. M = 56. 70°. Both the left and the right fibula showed no significant difference （t = 0. 308, P = 0. 758）. Angle B was ranged from 32. 17° to 33.44°, x = 32. 80±° ±6. 49°, M = 32. 90°. Correlation-regression study found that there was negative eorrelation （ r = - 0. 952, P = O. 00） and signifieant difference （ t = 51.87, P 〈 0. 01 ） between angle A and angle B. Conclusion There was no difference between the results by 64-row spiral CT and by bare bone to measure the slope of proximal tibiofibular joints, which proves that it is preeise, convenient and no wound by the measurement of CT. It will be easy to build the large sample database
